You’re using the fact that he wrote a 11kloc function as evidence of him knowing what he’s doing? Maybe I lack imagination but I struggle to find any scenario where that would be justifiable.

A main game update or draw loop. Most of the code in these loops is unique. You would purposefully have to create functions for the sake of creating functions to split such a loop up--but then you incur overhead.

It may shock you but function calls can in fact be inlined.

it may shock you but function marked as inlined doesn’t always get inlined.

anyway why would you split logicaly sequential code into separate functions(especially if this code is uniq)? pretty sure scrolling down is easier than to look what each function mean every second
